Joy of the Day 23/365 is honeybees.
Remember a couple years ago when there were dire predictions that all the bees would die out in the world, and then humanity had only four years to live, because the bees' pollinating crops is so crucial to our food security?
Well, that turned out to be something of a false alarm. That's not to say the bees weren't in trouble -- they were. They still are at an all-time population low. But the threat of imminent collapse isn't so much a thing. The pesticides that were part of the problem have been banned, and other causes were shown to be non-issues. We could always do more to ensure sustainability. Nonetheless, the bees are back. Whew.
